Prelude is a Universal "Security Information Management" (SIM) system.
Its goals are performance and modularity. It is divided in two main
parts :
- the Prelude sensors, responsible for generating alerts, such as
snort sensor, featuring a signature engine, plugins for
protocol analysis, and intrusion detection plugins, and the Prelude
log monitoring lackey.
- the Prelude report server, collecting data from Prelude sensors,
and generating user-readable reports.
